Inspired by geometry, researchers built an aircraft that propels itself through the air by turning itself inside out. The SmartInversion, designed by the German company
Festo, is an airborne geometrical band with an inversion drive. The lightweight triangular-shaped craft is filled with helium and has electrically-activated joints controlled by a remote control. So-called "inversion kinetics" propel the contraption forwards. The video is mesmerizing.
